SPECIFICATION forming part of Letters Patent 1%. 670,238., dated March 19, 1901.

Application filed May 10. 1898.

To all whom it may concern.-

e it known that I, JOHN W KELLY, a citizen of the United States, residing at New Brighton, in the county of Beaver, and State of Pennsylvania, have invented certain new and useful Improvements in Drain or Sewer Pipes; and I do declare the followingto be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure l is a longitudinal sectional view" iron or terra-cotta, are commonly provided wii h a socket at one end into which the smaller end of another section is inserted when the pipe is placed in position for use. It is important that the end-of one section should be so related to the end of the abutting section that no ridge or projectionwill be formed across the interior of the pipe to serve as an obstruction to the flow of water and to catch and retain any solid matter that may be carried by the water. Various means have been heretofore proposed for properly supporting" the smaller or spigot end of such a pipe-section in position within thcenlargzed socket at the adjacent end of another section. Commonly the pipe-setter adj nsts the spigot end of the pipe and retains it in proper position l 'ineans oftsmall pieces of brick placed between such spigot end and the surrounding it has also been proposed to form a log; or outwardly-extending projection on the socketwall, this projection being arranged near the on ter end of the socket and designed to extend below the spigot end of the section placed in said socket. But when either of the plans above referred to is followed it will be seen that there isnoassurance that tlieTwo Serial No. 680,286. (No model.)

sections of pipe will be correctly alined-that is, when the socket at the end of a pipe-section A (see Fig. 1) is provided near its outer end with an outwardly-extending lug a it will be seen that unless the spigot end is of such diameter as to extend completely across the space between the upper surface of theluga and the inner surface of the socket a, diametrically opposite said lug, a slight pressure another section can be accurately and correctly placed in the socket and held in true alinement with the body of the section until the cement, lead, or other fastening material has been introduced into the socket and around the spigot.

Referring to the drawings and p'articnlarly to Figs. 2 and 3, D Edesignate two similarlyformed pipe-sections, each being provided at one end with an enlarged socket F. Within the socket F and at the inner end thereof I arrange a series of in wardly-extending lugs G. These lugs, which may be formed integral with the pipe-section,ai'e preferably made in the fornrshown-that is, each has a surface g extending parallel to the length of the pipe-section, and an inclined surface g extendingfrom the aforesaid surface g to the inner sn rface of the socket F. outer ends of the lugs G are some distance within the outer end of the socket F, and said lugs are of less thickness than the distance which the socket F projects radially from the body of the pipe. In the drawings I have shown the socket as provided with three of these inwardly-extending lugs G, arranged equidistant from each other; but anysuitable number may be employed.

From the above description and the drawings it wili be seen that when the spigot end of the section E is inserted into the socket F of the section I) the inclined surface gof the- As shown, the

'5 spigot should have any lugs G will causeitsinner end to be properly guided into position of alinement with the passage in the tube section D. .It will also. be seen that I so arrangeflthe lugs G that the spigot end is held from eitlierleteral or vertical movementybu t isadapted to revolved or turned about the longitudinal a ds in order that the two ends" of the section's D E may be arranged inthe best-possible relation to each other; It frequently happens-that these pipes are not perfectly true circlesin crosssection, and by m con'strdction the pipe-set ter is enabled to rotate the spigot un-" til the flow-line of the section E is prop erly related to the section D. Again, if a irregular outwardlyextending projection it could be so placed as to have such projection lie between lugs G. One of the great advantages incident to my improved construction is that the pipe-sections-do not have to be placed in any predetermined axial position to permit of the proper alinement thereof one with relation to another-that is, my improvements guished from such a construction as that illustrated in Fig. 1, for example, wherein the pipe-section must always be so arranged that. the lug ct will be at the lowest point. My improvements as pointed out above permit the pipe-section to be turned axially until the best possible alinement with the preceding section is obtained, the lugs G being in working position at all times in every position of the'pipe-section.

By referring to the drawings it will be seen that the socket F is concentric with the body of the pipe-section, and as the lugs G are arranged at the inner end of the socket it is possible to readily make the sections by maare distinas the said lugs form no obstruction to the movement 0 the former away from the pipe after the same been made, and the inner end of each lug is integral with the shoulder part of the pipe at the socket -that is, the shoulder where the body part terminates and widens out vide the socket. There is no open space whateverlietween the inner ends of the lugs and chinery,

the shoulder. Hence the mandrel or former around which the pipe is shaped can he withdrawn as readily and safely as if no lugs were 1 present; After the pipe-sections DE have been properly alliiied they are secured together in the ordinary manner by cement, lead, or other i fastening matter, according to the material of which the pipes are formed. What I claim is-- I A pipe-section having at one end a socket of greater diameter than the body part and formed with three tapering lugs integral with the socket-wall and with the end of the body part whereby other bodies are prevented from -oatching behind thelugs,and having its spigot end formed with a continuously smooth external surface, whereby it is adapted in' any of its axial positions to be inserted into an adjacent socket such as described, and be guided by the tapered surfaces of the lugs into proper alinement and held against either vertical orlateral displacement, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
